Aaron Eckhart as Harvey Dent in The Dark Knight

Who would’ve thought Two-Face actually leads a double life? Aaron Eckhart, the actor who played pretty-boy-lawyer-turned-scarred-villain Harvey Dent in The Dark Knight, has another passion that has nothing to do with acting: photography.

“I’m obsessed with it–it’s all I do,” the 42 year-old actor recently told People. “That’s really the only thing I think about.”

Eckhart recently shot a photo campaign for a jewelry line produced by model and close friend Molly Sims. At the line’s release in New York City he talked about what he most looks forward to in starting a career in photography, as well as what he wants to stay away from.

“Straight-up fashion photography in the studio–that’s not what I necessarily aspire to, you know? I like to be outside, on location, making up stories,” he said. “That’s where my acting comes in.”

Eckhart, who received a Golden Globe nomination in 2006 for his role as a smooth-talking spokesman for the tobacco industry in the dark comedy Thank You for Smoking, cites photographers like Peter Lindbergh and Bruce Weber and magazines like French and Italian Vogue as inspirations.

While he may not be a professional photographer yet, Eckhart definitely has the passion and curiosity to turn it into more than just a hobby.

“I’m really just a photography geek,” he said. “I just love to shoot.”
